Formed on the forward end of the section 7 is the extension 9. Projectionssuch as are illustrated at 10 and v1l'respectivelyin the drawing are also arranged on the forward portion of the section 7 adjacent the extension 9 in the manner clearly illustrated in Figure 4. j L

l/Vhen the section 7 is brought into position over the section 6 and theysame are in the tmanner clearly illustrated in Figures l and 3 of the drawing.l kThe purpose of the laterally extending projections 10 and l1 will hereinafterbe more fully described. Thev slots 8 in the socket portion 5 serve to provide a plurality of resilient fingers adapted through their'resiliency toA Contact with the shank portion of the file seated therein, and to firmly hold the same,

and files of varying sizes within predetermined limits.

Cooperating with the socket member 5` and providing` a handle for the `file isv the member 12 and the saine comprisesa lplurality of convolutions of wire, the same tapering gradually from the center of the handle toward the end lthereof in the manner clearly illustrated in,` Figures l and 2. The forward end of the fhandle l2 extends yover the forward portion of the socket inem- Y socketmember on the shank portion of the file. i,

In use, the projections l0 and lljon the forward portion ofthe socket member are disposed in the foremost convolution ofthe wire handle l2 so as to facilitate theinser-` tionv of the shank portion 2 of the file in` the socket member, it being understood that the forward end of the file is disposed yin engagement ywith the hook l on the forward end of the cover or strip 3. After the i'ile has been inserted in proper position, the handle l2is thenl turned so as to cause the projections l0 and 1l to travel in the convolutions 18 whereby a binding action `on the split socket member 5 will be obtained to above mentioned character, enables a person using the file to place one hand on the cover which entends over the upper surface of the lile while the other `hand is employed in holding the handleand the cover will prevent the person from having his hand come in contact with the upper cutting surface of the iile when bearing down upon the saine during its use. When one of the cutting surfaces has become worn, theattachment may be readily removed from the lile and reversed so that the cover will extend over the wornsiirface of the file and enable the opposite side to be used. The simplicity of `my device enablesjthe same to be readily and easily adjusted in position on a file andinay furthermore be used in connection with files of various sizes. A device of thechar acter above described will not only be yetlicient and positive in'` its operation in securing the attachment in position on a file but willalso be inexpensive 'as well as strong and durable. f

`While l have shown the preferred embodi-v ment of my inventioinit is to be understoodl as well as permitl of the insertion of Shanks that various changes in the size,` shape and arrangement ofparts may-be resorted to without departing from the spirit of the invention and the scope of the appended claims.

. Having thus described l claimr is l. An attachment for ytiles comprisingian elongated strip of metal extending over the upper surface of the file, a hook formed on the forward end thereof" `for engagement withk the'forward end of the file, a socket inembervon the rear end of the strip receiv? ing the shankportion of the rrear end of the file, and a handle member.

2. `An attachment for files comprising an'y elongated strip of metal extending over the upper surface of the file, a hook formed on the forward end thereof for engagement withA the forward'end of the file, a socket member onv the rear end of the'strip` receive ing the shank portion of the rear end of the file, a handle extending over the socket member, said socket member .being slit longitudinally, .laterial'projections at diametrically" opposite points on the forward portion of j the socket member, and having means for cooperation with the lateral projections for` causing a binding action on the socket member when the handle is turned, whereby the file is secured in the socket member against accidental disengagement therefrom.

3. rin attachment for files comprising an elongated strip of metal extending over the j upper surface of the file, a hook formed on the forward end thereof for engagement with the forward end of the file, a socket n member on the rear end of the strip receivr ing the shank portion of the rear end of the the invention, what extending over the socket.

file, a handle extending over the socket mem ber, said socket memberbeing slit longitudinally, lateral projections at diametrioally opposite points on the forward portion 0f the soolet member, said handle comprising a series of convolutions of wire gradually tapering from the center' toward the ends thereof, said projections Cooperating with the convolutons for causing a binding aoton on the socket member when the handle is turned whereby the shank portion of the le is Secured inv the'sooket member against accidental displacementv therefrom. i In testimony whereof I aHiX my signature. l
